FIG. 1 is a perspective view illustrating a conventional foldableelectronic device. Referring to FIG. 1, a conventional foldableelectronic device 10 may be implemented as a foldable portable terminal,and may include a display 11 that is concealed from the outside in thefolded state. The display 11 may display an image. In the state wherethe electronic device is folded, the display 11 may be concealed by theelectronic device 10.

The electronic device 10 may be provided with a cover 12 that is formedof a flexible material, such as a leather material or a rubber material,so that the sense of an exterior design can be diversified. Theelectronic device 10 may be configured to be foldable so that theelectronic device 10 can be conveniently carried.

However, in order to use the electronic device 10, it is necessary tounfold the electronic device 10, which may be troublesome andinconvenient. Thus, the teachings of invention addresses the drawbacksof conventional foldable device, as explained hereinafter.

FIG. 2 is a perspective view illustrating an electronic device accordingto a first one of various embodiments of the present disclosure. FIG. 3is a cross-sectional view illustrating the electronic device accordingto the first one of various embodiments of the present disclosure. FIG.4 is a rear view illustrating the electronic device according to thefirst one of various embodiments of the present disclosure. FIG. 5 is across-sectional view illustrating the electronic device according to thefirst one of various embodiments of the present disclosure in the foldedstate.

Referring to FIGS. 2 to 5, according to one of various embodiments ofthe present disclosure, an electronic device 100 may include a firstdisplay device 101, a cover 103, and a second display device 105. Here,the electronic device 100 may be a portable terminal. However, theelectronic device 100 may be any of various electronic devices thatinclude a foldable display (e.g., a flexible display device) withoutbeing limited to the portable terminal.

The first display device 101 may include a body 113 and a flexibledisplay device 111, and may be an image displaying device that isconfigured to be foldable. The body 113 may include a circuit unit(e.g., a circuit board) that processes communication, various pieces ofinformation, or the like, a battery that supplies power, etc. The body113 may be folded or unfolded. The flexible display device 111 isprovided on the front face of the body 113, and may be folded orunfolded together with the body 113. The flexible display device 111 mayoutput an image under a control of the circuit board included in thebody 113, or the like. For example, the first display device 101 mayinclude the flexible display device 111 so as to operate as an imagedisplaying device.

The cover 103 is provided on the rear face of the body 113 to befoldable together with the body 113. The cover 103 may be formed of aflexible material, such as a leather material or a rubber material.However, the material of the cover 103 is not limited to the flexiblematerial. A portion, which is deformed in a curved shape at a foldingoperation, of the cover 103 may be formed of a flexible material, andthe cover 103 may also include a portion, which is capable ofmaintaining a predetermined shape regardless of the folding operationand that is formed of a rigid material, such as, for example, a plasticor a metal. Accordingly, a portion of the cover 103, which is capable ofmaintaining a predetermined shape even at the folding operation, may beprovided with components that are required for the electronic device,such as a circuit unit (e.g., an antenna radiator).

The second display device 105 may be disposed, for example, on the rearface of the body 113 to be opposite to the flexible display device 111.As illustrated in FIGS. 3 and 4, the second display device 105 may beconcealed by the cover 103 in the state where the body 113 is unfolded.In addition, when the body 113 is folded, for example, when twodifferent portions of the body 113 are folded in the direction where thetwo different portions face each other, a portion of the rear face ofthe body 113 may be exposed depending on the thickness of the electronicdevice 100 and the curvature in the folded state, as compared to thestate where the body 113 is unfolded. For example, as illustrated inFIGS. 2 and 5, the second display device 105 may be exposed to theoutside of the cover 103 in the state where the body 113 is folded. Thisis caused due to a difference in relative displacement between the firstdisplay device 111 and the cover 103 at the folding operation. The firstdisplay device 111 and the cover 103 may be coupled to be at leastpartially slidable in relation to each other.

As the second display device 105 is exposed in the state where theelectronic device is folded, various pieces of information, such asweather information, time, phone call reception, and text messagereception, may be output through the second display device 105.Accordingly, the user may use the electronic device 100 while confirmingvarious pieces of information through the second display device 105 evenin the state where the flexible display device 111 is folded.

In addition, when a touch screen function is incorporated into thesecond display device 105, a displayed icon may be changed or anoperation mode of the electronic device may be changed according to theuser's touch input.

Referring to FIG. 5, while one end of the body 113 and one end of thecover 103 are fixed to each other at a first fixing portion 107, thecover 103 may be coupled to the body 113 to be at least partiallyslidable. Accordingly, when the electronic device 100 is folded, theother end of the cover 103 may move toward the central portion of thecover 103 such that a portion of the rear surface of the body 113 can beexposed. By arranging the second display device 105 in the region thatis exposed according to the movement of the cover 103, the seconddisplay device 105 may be exposed to the outside of the cover 103 as thefirst cover 103 is slid.

FIG. 6 is a perspective view illustrating the electronic deviceaccording to first one of various embodiments of the present disclosurein the folded state. FIG. 7 is a illustrating a joint portion of FIG. 6in an unfolded state.

Referring to FIGS. 6 and 7, according to the first one of variousembodiments of the present disclosure, the electronic device may includea plurality of joints 109. Each of the joints 109 may include a firstfacing portion 191, a second facing portion 193, and inclined portions195. The first facing portion 191 may face the first display device 101.The second facing portion 193 may have a length that is shorter thanthat of the first facing portion 191, and may face the cover 103. Theinclined portions 195 interconnect the opposite ends of the first facingportion 191 to the opposite ends of the second facing portion 193,respectively, and may be inclined relative to the first facing portion191. Even if the first display device 101 are folded in the direction inwhich the two different regions face each other, the plurality of joints109 are placed in the state where the entire length of the surface, onwhich the first facing portions 191 are arranged, may be maintained tobe the same as the unfolded state. For example, at the folding orunfolding operation, the joints 109 may stably support the first displaydevice 101 while causing the first display device 101 to be deformed ata proper curvature. On the contrary, at the folding operation, in theportion that is deformed in a curved shape, the length of the cover 103,which is arranged on the second facing portions 193 may be changed bythe change in distance between the second facing portions 193. Thechange in the length of the cover 103 in the portion that is deformed inthe curved shape may move the other end of the cover 103 toward thecentral portion of the cover 103.

As described above, according to the first one of various embodiments ofthe present disclosure, since the electronic device 100 includes aplurality of joints 109 that face each of the first display device 101and the cover 103, at least a portion of the cover 103 may be relativelymoved in relation to the first display device 101 in the state where thebody 113 and the cover 103 are folded.

FIG. 8 is a view illustrating a relationship between a region in whichthe second display is exposed and a cover, which are applied to theelectronic device according to the first one of various embodiments ofthe present disclosure. First, with reference to FIG. 8, a center line“L”, a radius “R”, a thickness “t”, a slope “a”, and a displacement “d”are defined. The center line “L” may be a virtual line thatinterconnects the center and the contact point of the opposite ends ofthe folded first display device 101. The radius “R” may refer to acurvature radius of a curved portion that is formed as the first displaydevice 101 is folded. The thickness “t” may refer to the thickness ofthe cover 103. The slope α may indicate an inclined angle of the firstdisplay device 101 in relation to the center line “L”. The displacement“d” may refer to the displacement of the other end of the cover 103 inrelation to the first display device 101.

As illustrated in FIG. 8, as the first display device 101 is folded, thecover 103 may be positioned at a radius (“R”+“t”) that is larger thanthe radius R of the first display device 101. When the lengths of thecover 103 and the first display device 101 are practically unchanged inthe portion that is deformed in the curved shape, the cover 103, whichhas the larger radius at the other end of the first display device 101,may move relative to the first display device 101 in the process ofbeing folded or unfolded. For example, as the thickness t of the cover103 increases, the relative movement of the cover 103 with respect tothe first display device 101 may further increase. Accordingly, thesecond display device 105 may be set to correspond to the displacement“d” that corresponds to the distance that the of the cover 103 movesrelative to the first display device 101. That is, the second displaydevice 105 may be set to correspond to the displacement that isproportional to the thickness “t” of the cover 103. For example, thesize of the second display device 105 may be set to correspond to thedisplacement that is proportional to the thickness t of the cover 103.

In addition, the relative movement of the cover 103 is variabledepending on the slope α. For example, when the slope a increases, theradius R of the first display device 101 may also increase, which mayincrease the relative movement of the cover 103 with respect to thefirst display device 101.

FIG. 9 is a view illustrating a guide that is applied to the electronicdevice according to the first one of various embodiments of the presentdisclosure. FIG. 10 is a cross-sectional view illustrating a first guideand a first guide hole, which are applied to the electronic deviceaccording to the first one of various embodiments of the presentdisclosure.

The first guide 131 may be formed to extend from the lower portion ofthe cover 103 and to protrude toward the body 113. The first guide 131may be formed in the longitudinal direction of the cover 103, forexample, along a direction in which the cover 103 moves relative to thebody 113. The first guide hole 115 is provided in the body 113, and maybe formed to correspond to the first guide 131. In addition, the firstguide 131 may be slid along the first guide hole 115 while beingrestrained by the first guide hole 115.

In this way, according to the first one of various embodiments of thepresent disclosure, in the electronic device 100, as the first guide 131is slid while being restrained by the first guide hole 115, the cover103 may correspondingly move relative to the body 113 without beingreleased from the body 113.

FIG. 11 is a cross-sectional view illustrating an electronic deviceaccording to a second one of various embodiments of the presentdisclosure in a folded state.

Referring to FIG. 11, according to the second one of various embodimentsof the present disclosure, because the first display device 201, thecover 203, and the second display device 205 of the electronic device200 are similar to those of the above-described embodiment, detaileddescriptions thereof will be omitted.

According to the second one of various embodiments of the presentdisclosure, the electronic device 200 may include a first region F1 anda second region F2. The first region F1 may refer to a region that isdeformed in a curved shape in the state where the electronic device 200is folded.
